Haven't talked myself out of it when i come across it too uAU i feel what you mean lol. A trick tho, i've made a point that _if_ i finish my next sketchbook i can set myself a date. Take myself out on an art date to get a new one. Making it more special and a dopamine hit can hit harder uvu <3

That friction can be best ignored the moment you open the document/journal. Try for 2mins. If it's time to write you'll stick to it. If there is more resistance. Get that coffee/tea and snack and come back and try again for another 2mins.

Just breaking that friction could be what's keeping you.

Honestly this is a mood and i feel for you. If you want advice try this:
-Changing location every hour. Set a timer to switch. Just the use of moving around can stir ideas.
-Body Doubling: Have someone with you in the same place doing something.
-Sit around other people/Cafe/Library/Park
